In carrying out the yrcsent invention; provide aremovable jacket, 10, which closeditt ite front, sides and to' ond' or at its bottom and rear. This 3fm-cet pf er'cbiy formed from a single piece oi i metal, euch as galvanized irontI oritiio inte, which moy be painted, eneineiedmr ott Wise treated, to Vpresent o ileaeinggg opy ance cndto odd to itsvduildiiity by prot mg against corrosion.' This jockot tit-o about and encioses the cooii-ng coils with it@ io end resting 'upon the bottom of the refrigerator directly over the drain D., end/With its open boeit closed .by the rear Woiii oi the l refrigerator. "Vorioos means may ino in, played for holding this: jacket in lg:

though in actual practice, 1 prefer turn buttons il, pivotcd on the back wall of the refrigerator and engaging over lateral flanges l2 iol-med on the sides of the jacket. This 'particular securing means permits ready removal oi' the jacket, whenever such may be found desirable. 'l`o allow for the inlet connection one side of the jacket may be cut away as indicated at i3.

At various points, the front of the jacket has a series oi openings 14 arranged opposite the spaces between the convolutions of the coils ll, and normally closed by doors 15 which are here illustrated as being hinge above the openings, but which mightrbe otherwise mounted.4 Extending rearwardly at the bottom of each opening is a shelf 1.6, which, in actual practice is preferably formed by bending rearwardly the metal of the front wall between the cuts defining ithe openings le, though l do not wish to be "restricted in this matter, as the shelves might be formed as separate pieces and soldered, riveted or otherwise secured to the front wall of the jacket about said openings. These openings and their doors are disposed above the shelves F, and access thereto may he obtained through the usual doors of the refrigerator. y

'lhe numeral 17 designates pans, in which is placed the water to be frozen, and these pans are here illustrated as being provided with various partitions 18, which form relatively small compartments. The pans are necessarily of a size to pass easily through the openinvs 14, and ey are preferaly provided with handlesv 19 which may consist merely of a rolled over edge. These details are stated, but theyare not material to this invention.

1n the use of the device, the doors 15 are swungopen, and the pans of water placed dll upon the shelves 16, after which the doors are allowed to return by'gravity to their closed position. The cooling actlon of therefrigerant passing through the coils will; o course, operate to'freeze the water in an obvious manner, so that when the pans are removed after the lapse of the required time, they ma be invertedto discharge or release the bloc s or cubes of ice, and replaced in the refrigerator for further use.

A feature of.my invention resides-in a a removable jacket forming an enclosure for the refrigerating coils and the ice pans supported in connection therewith, which enclosure. forms a place for freezing the water in the ice pans. This jacket or enclosure has no additional. insulation, as the usual insulation of the refrigerator answers all the purposes. '.lhe jacket extends from the top to the bottom of the coolin coil, enclosing the entire coil, andv at the liottom connects with the drain O, which as before stated, .1 purpose of a drain for therefrignection with the rear wall of the refrigerator, and this is the most desirable arrangement, it could be applied to one of the side Walls with satisfactory results. The invention does not materially trespass upon the food-receiving compartment of the refrigerator.

By reason of the fact that the cooling coils are enclosed and the refrigeration is con fined thereto, the contents of the ice pans may be quickly frozen without lowering the temperature of the refrigerator beyond the usual degree.

From the foregoing description, and a study of the drawings, it will be apparent that have thus provided a simple and practical means for producing ice for domestic or other purposes, the jacket operating to concentrate the cooling action of the retrigerant passing through the coil so as to elect vthe freezing without employin a refrigerant circulating at an excessivgly low temperature. As the attachment is so simple, its cost will be low while it will eliciently operate to dperform the function for which it is intende What is claimed isz- 1.\ In a rerigerator`having a provision chamber, the combination with a vertically extending cooling coil through which is passed a refrigerant a jacket forming with the refrigerator wall an enclosure for the coil and also forming one of the walls of the provision chamber, said jacket having openings opposite certain spaces between the convolutions of the coil, and supports at the openings extending into the enclosure for supporting water pans.
